Can an EEG (electroencephalogram) detect brain tumors?

No: Eeg can show presence of seizure brain wave activity.These seizure brain activity can be caused by different conditions such as metabolic abnormality, lack of blood supply to brain cells, medication, epilepsy, brain tumor related, etc. It analyzes the brain "function" not the anatomy thus it can't detect brain tumor specifically. Mri needs to be done to detect brain tumors. Discuss with your md. ...Read more

Genetic Testing (Definition)

Prenatal testing for genetic problems may be done before or after conception. Testing for spina bifida or Down syndrome is done after a pregnancy is established. Besides the couples listed above, counseling and diagnosis are also recommended for mothers over the age of 35, and those who have received abnormal screening test results, such as alpha-fetoprotein (AFP). For more information about the alpha-fetoprotein test, and when and why you might have it, see alpha-fetoprotein. For those who may be at risk, genetic counseling and prenatal diagnosis are used to help ...Read more

Do ovum donors undergo genetic testing or pedigree evaluation?

Do ovum donors undergo genetic testing or pedigree evaluation?

Does an abnormal EEG confirm epilepsy in you?

Does an abnormal EEG confirm epilepsy in you?

Yes and no: The eeg is a tool to be used by a trained neurologist to help diagnose epilepsy. The eeg alone is of little value. The history and examination are the important elements. Eeg recorded during a seizure can be very helpful but difficult to obtain. Baseline eeg can show abnormal activity, especially in children, even though the patient has never had a seizure. It is valuable in the right hands. ...Read more

Clarification: You have multiple issues, and most would strongly implicate MS. But if an MRI of both brain and spinal cord is normal, you do NOT have MS. However, several other possibilities exist, and you need to clarify your diagnosis. May help to obtain another opinion. ...Read more

Please exlain alpha-fetoprotein testing for genetic disorders?

Alpha fetal protein: AFP is a fetal specific globulin, synthesized by the fetal yolk sac, gastrointestinal tract, and liver. The function of AFP is unknown. AFP blood levels can be measured during the second trimester to screen for open spina bifida and anencephaly, but can also uncover fetal abnormalities such as abdominal wall defects. AFP is also used in screening tests for downs syndrome and edwards syndrome. ...Read more

Sev. Dev. Delay -array comparative genetic hybridization (acgh) results indicate no abnormalities- would full genetic sequencing be advised (knome)?

Not necessarily: Newer genetic tests provide incite into a variety of issues like autism & other developmental variations.Yet causation remains elusive in many cases.Sadly, an injury to the developing brain centers from an unrecognized event in an otherwise normal pregnancy is a likely cause for many.This occurs in at least half of cerebral palsy cases & dev.Delay could be produced in others, yet hard to prove. ...Read more
